This was my experience with the one I had and I hated it so much I only kept it 6 months - stew as dialling in front and rear for me it was either too firm at the back or too soft at the front and vice versaHad 2016/17 1290 gt. Suspension could not be dialed in. Either sea sick inducing wallow, or too firm, causing stability issues on bumpy roads.
Any way I have a 1390 SDR Evo and the suspension on this is the best suspension I have ever had - it really is sublime so when that tech gets to the GT .....
